When Ryan and I booked John from Popeye’s Postcards onto the show, I knew the headline number was that he’d bought a million postcards in one shot. I did not know the rest of it — that he’d flown across the country to do it, that he’d been the very first postcard seller Whatnot ever onboarded, or that he runs the whole operation out of a wall of shoe cubbies that look like a small-town post office. This one’s a tour through how a niche category becomes a full business when somebody decides to take it seriously.

A million postcards. $10,000+. He flew there.

[0:00] John doesn’t bury the lede. He bought a million postcards from a single source. The price was north of $10,000. The deal was big enough that he flew across the country to inspect the lots in person before committing — because at that volume, you don’t FedEx a sample box and hope. You go look. You make sure the cards are what the seller says they are, you negotiate in the room, you arrange the shipping, you get on a plane home. That’s the acquisition. Listing them is the next twelve months of his life.

[10:00] 46,000 cards in the main store right now. John keeps 46,000 active listings in his eBay store. Even at that volume, there are slow days — “I might sell two cards for $16.” And there are good days where he runs three big sales in a row. Postcards are a long-tail category and he’s playing the long tail on purpose.

Whatnot’s first postcard seller

[20:00] When Whatnot opened up to non-trading-card categories, John signed up early enough that he was the first postcard seller on the platform. They onboarded him over a video call — “Tell me what you sell” — and he had to explain the postcard market to a category manager who had never run a postcard show. Ryan and I have been picking at the Whatnot question for weeks (Josh from Hairy Tornado made the case last week); John’s experience is a different angle. If you’re early on a new category on a new platform, the audience is yours to define.

”That’s my grandfather on that postcard”

[1:00:00] The story I keep thinking about. John listed a 50-some-year-old postcard for $15. An hour after the listing went up, a buyer messaged him: “That’s my grandfather on that postcard. Will you take less money for it?”

John said no.

He framed it the way it actually is: “This is how I make my money. I just listed this an hour ago. I’m not going to drop the price because of a personal connection — that’s the eBay price.” It’s the kind of message that makes you want to drop the price. John drew the line and didn’t. There’s a longer conversation in the episode about what that line costs and what it earns, and I think he’s right but I also understand why someone hearing the story for the first time might bristle. Worth listening to.

The shoe-cubby sorting wall

[45:00] John’s storage system is a wall of 5×5 shoe cubbies — about 75 to 80 slots — turned into a postcard sorting grid. He compared it to a mail-sorting center, which is the right metaphor: incoming bulk gets sorted by category into the cubbies, then individual cards get pulled into listing batches by topic. If you’re running ephemera at any volume, this is a system worth stealing.

The turkey, the cigarette, the sunglasses

[1:45:00] John pulled out a postcard featuring a turkey wearing sunglasses and smoking a cigarette. “It’s just weird stuff. I mean, I don’t care what — the pig can love who it wants to love.” The episode has a lot of moments like this — niche catalog deep cuts that nobody else is going to show you, because nobody else is sitting on a wall of postcards from every weird era American printers ever produced.

The closer

[2:00:00] John closed by talking about imposter syndrome — and Ryan caught it: “For me to hear you beat yourself up over something like that, given what you’ve done and executed on… it’s just really something.” That’s a recurring theme on the podcast and I don’t have a clean answer for it, but it shows up often enough that it’s worth naming.
